Officials warn residents to avoid California beaches as massive waves pound the coastline, prompting high surf warnings from Ventura to Los Angeles County. Visitors at Pismo Beach are stunned by the heights of the swells, some reaching up to 25 feet. The Ventura Pier has been closed due to these hazardous conditions. With atmospheric rivers expected to bring further rain and winds, communities remain on edge as the potential for coastal flooding escalates, particularly during the holiday season. Surfers are braving the treacherous waves, but authorities emphasize the dangers posed by persistent high surf and advise caution for anyone near the coast.
